Helmet Sizing Information.To achieve proper helmet fitment, begin by finding your head circumference size using the method described below. Remember that the helmet sizing you choose should fit around the crown of your head comfortably with no pressure points. The cheekpads should fit firmly around your face. Once your chin strap is fastened, grab the chin bar of the helmet and move it side to side. Your cheeks should move with the helmet, which should not slide across your face. Different thickness cheekpads can be purchased to obtain the perfect fit. Head Measurement Instructions. Wrap a flexible tape measure around your head approximately one inch above your eyebrows and ears. Use this measurement (in either inches or centimeters) to find your helmet size in the chart below.
The Airframe is Icon’s highest level traditional style full face helmet, with a fiberglass, Dyneema, and carbon fiber shell. They meet what Icon calls the All World Standard. This means that these helmets meet the required safety standards in the four largest motorcycle markets. They are DOT approved for the U.S. market, ECE approved for the European Union, SAI for the Ausies, and SG for the Japanese. The Airframe comes in sizes small to two X, and the shell has a medium oval shape. Since most American riders have this shape head, these helmets fit a lot of heads. Unfortunately, mine isn’t one of them. According to the size chart, I should wear a large. This is an XL and still puts quite a bit of pressure on my five head. If you like Icon brand helmets, but have a long oval head like I do, be sure to check out the Airmada or the Variant, as both of these models have long oval shell shapes. Let’s look at some features. Starting with the ventilation, we have a two position chin vent that’s pretty easy to operate with gloves on and helps with shield fog maintenance. At low speed, you can unlock the Prolock on theface shield as well, for some additional fog management. There are two additional vents on the chinbar here on the sides. These are also adjustable with rotating dials inside of the helmet. These vents work well, but it can be tough to open or close them with gloves on. Some riders will even need to take the helmet off, or select your desired setting before you put the helmet on. Moving up the face we come to the three position dual port forehead vent. These vent ports are controlled by a single switch in the middle of the assembly. Air is pulled into these vents by the low pressure venturi effect that is created at the back of the helmet at the exhaust ports. The rear spoiler works with this venturi effect to minimize buffeting at speed. There are additional exhaust ports near the bottom of the helmet as well. Next we’ll take a look at the Fog-Free Icon Optics face shield. This is not the easiest to use quick release shield system out there, but it is still very good for a shield with covered side plates. If you open the shield all the way to the up position, you will expose the orange lever that is used for shield removal. Just slide it forward and the shield will pop right off. If you are reinstalling a different shield, you will have to remove and reinstall the side plates. To get them off, you need to get your finger behind the straight edge of the side place and pull outward. When reinstalling, Icon recommends installing the faceshield onto the helmet first, then snapping the side plates back into place. Now let’s get a better look at this Hydradry liner setup. Hydradry is Icon’s moisture wicking and antibacterial liner material that wicks the moisture away from your head keeping you more comfortable in warm weather. This liner is also removable, so that it can be rinsed or washed to prolong its life. A good indicator that your liner needs to be washed is that you are getting sweat in your eyes. When the wicking cells of the liner get packed with salt from your sweat the material stops absorbing moisture. Washing the liner will restore your liner’s absorbency and make the material soft again. To remove the liner, unsnap the cheek pads from the eps and remove them. Then unsnap the head liner from the back to the front. The breath guard and chin curtain are also removable by simply pulling up and/or out on them. While we have the liner out, you can see the dual density EPS liner that does the bulk of the shock absorbing.
